Trans 4 (N,N ′ dimethyl amino) 4′ ( N,N′ diethyl amino) stilbene (DMAEAS) has been synthesized and characterized by 1H NMR spectra, IR spectra, and elemental analyses. Its linear absorption, single photon induced fluorescence and two photon induced fluorescence are experimentally studied. This new dye has a great two photon absorption (TPA) cross section of σ 2=1 16×10 -46 cm 4·s/photon at 532 nm by using an open aperture Z scan system. When pumped with 800 nm laser irradiation, DMAEAS shows a strong two photon induced blue fluorescence of 440 nm.
